STATS INCANDESCENT GAS-LAMP.

To all 'whom t may concern:

Be it known that I, EDWARD MINEER, a citizen of the United St-ates of America, and resident of lVheeling, county of Ohio, and State of Test Virginia, have invented certain new and useful Improvements in Incandescent Gas-Lamps, of which the following is a specification.

This invention relates to improvements in gas lamps, and more particularly to a gas lamp of the type wherein the burners are inverted; and it consists in the particular construction, arrangement and combination of parts which will hereinafter be fully described.

The primary object of the invention is to provide a lamp of the incandescent invertedburner type wherein the radiated heat will be quickly conducted away from the burners, preventing excessive heating of the latter.

Other objects are to provide a lamp which is extremely simple, inexpensive and durable in its construction, a lamp having burners composed of but few connected parts, and a lamp having conveniently arranged and operated regulating means.

In describing the invention in detail, reference is herein had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side elevation of the invention; Fig. 2 is a vertical sectional view of the same; Fig. 3 is an enlarged sectional view of a burner, showing the regulating means therefor; and Fig. 4 is a horizontal sectional View on the line 4 4, Fig. 2.

Referring to said drawings, in which like reference numerals designate like parts throughout the several views-1 indicates a vertical gas-supply pipe, from the lower' end of which the lamp constituting this invention is suspended. rIhreaded upon the lower end of the pipe 1 is a cap 2 in which are threaded the ends of a plurality of horizontal arms 3 each of which is formed integral with a regulator box 4 which has extending from its top to a point near its bottom a central bore 5. The upper end of said bore is threaded for the reception of a regulating needle 6 which is adjustable in said bore for moving its point with relation to the small gasfeed aperture 7 which communicates with said bore and opens outward through the bottom of said box.

Screwed upon the lower end of the box 4 Specification of Letters Patent. Patgntd NOV, 15 191()a Application filed March 12, 1909. f

V12 which is shown as screwed into and depending from a heavy metal bell or shield 13, but which may be formed integral with the latter, and the lower end of the mixing tube S is received within the upper end of said tube 12.

The bell or shield 13, which is adapted to receive the heat emanating from the burners and thus to prevent injury to a sheetmetal cover 14, is circular in form and has a central hollow upwardly-directed neckportion 15 which receives support from the arms 3. Embracing said neck-portion is the lower end of a cylindrical sheet-metal casing 16 which is adapted to conduct the heat and products of combustion upward and away from the burners, preventing undue heating of their mixers and regulators. The upper end of the casing is preferably provided with a canopy-top or deflector 17, as shown.

Overlying the shield 13 and projecting outward beyond the edge of the latter is the sheet-metal cover 14 hereinbefore referred to, said cover being turned downward vertically to form an annular vertical flange 18 in which are a plurality of air-inlet openings 19 for supplying fresh air to the interior of a globe 20 which incloses the mantles, which globe is preferably of the swinging type, being hinged at one side to the flange 18, as shown at 21, and being detachably connected thereto at the opposite side by a suitable latch 22.

, It will be noted that the arm 3 and regulator box 4 are formed integral and that the usual nipple screwed upon the lower end of said box is dispensed with, thus avoiding the use of the usual threaded joints which afford opportunity for leakage. It will further be noted that the parts composing each burner may be easily and quickly removed and assembled without disturbing the parts composing the body of the lamp.

Not only is the construction of the lamp such as to prevent undue heating of the burners, but it affords a steady or constant draft whereby the products of combustion are delivered away from the lamp and a steady and even flame promoted in the mantles which insures a. uniform degree of luminosity. Y Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a gas lamp,apendent supply-pipe, a plurality of radial conducting arms threaded into said pipe, an integral regulator box carried by each arm, a heat-deflecting shield suspended from said arms, vertical mantlesupporting tubes depending from said shield, mixing tubes suspended from said regulator boxes and having their lower ends received in said mantle-supporting tubes, and a casing for receiving and discharging the products of combustion at a point remote from the mixing tubes. l

2. In a gas lamp, a pendent supply-pipe,

a plurality of radial conductingV arms con Vneoted to said pipe, regulating means carried by said arms, a heat-deflecting shield suspended in a substantially horizontal position below said arms, vertical mantle-supporting tubes depending from said shield, mixing tubes suspended from said regulating means with their air openings located above said shield and having their lower ends received within said mantle-supporting tubes, and a easing mounted centrally upon said shield for conducting the lproducts of combustion away from the mixing tubes.

In testimony whereof I aiiix my signature f in presence of two subscribing witnesses.

EDWARD MINEER.
